“…Fear, panic attacks and syncope can be the main symptoms in the early stages of TLE (McLachlan and Blume, 1980; Hermann et al ., 2000; Biraben et al ., 2001), which can often lead to misdiagnosis as primary psychiatric disorders for years prior to the development of more classic ictal semiologies (Thompson et al ., 2000; Mintzer and Lopez, 2002; Sazgar et al ., 2003; Kanner, 2011). After treatment with antiseizure medications, the majority (68%) of patients with “neurovegetative” and psychiatric symptoms, with RTTBD patterns on EEG, improved clinically, and the RTTBD pattern became less frequent ordisappeared (Stone et al ., 1986; Muller et al ., 1988; Gibbs and Gibbs, 1989). This suggests that RTTBD might be an early ictal EEG marker for TLE, which would account for the poor correlation between the incidence of RTTBD on EEG and epilepsy.…”

Aim. To determine clinical and intracranial EEG correlates of rhythmic temporal theta bursts of drowsiness (RTTBD) and assess its clinical significance in patients with temporal lobe epilepsy (TLE). Methods. A retrospective review of simultaneous scalp and intracranial video‐EEG recordings from 28 patients with TLE was evaluated for epilepsy surgery. Scalp RTTBD patterns were identified and their clinical and intracranial EEG correlates were then determined on video‐EEG recording using depth and subdural electrodes. Results. Thirty‐one RTTBD patterns on scalp EEG were observed in six (21%) of the 28 patients. Five (16%) of the RTTBD patterns occurred during wakefulness and 26 (84%) occurred during drowsiness and light sleep. The mean duration of RTTBD was 10 seconds (range: 3‐28 seconds). RTTDB consistently correlated with hippocampal ictal discharges and was time‐locked to the hippocampal seizures in which the ictal discharges evolved into rhythmic theta frequency (4‐7‐Hz) range. Ictal automatisms were observed during five (16%) RTTBD patterns, while cognitive impairment was observed in four (13%) of the 31 RTTBD patterns. Conclusion. Our findings show that scalp EEG correlates of hippocampal ictal discharges can resemble RTTBD and may be associated with ictal symptoms and cognitive impairment, indicating that RTTBD may rarely be an ictal EEG pattern in patients with TLE.

Infrequent occurrence of EEG abnormalities in panic disorder

EEG abnormalities have been frequently reported in patients with panic disorder, although controlled studies are lacking. The authors examined the EEGs of 35 consecutively evaluated, medication-free patients with panic disorder and found that only five (14%) had nonspecific abnormal EEGs and none displayed EEG evidence supportive of an ictal process. The presence or absence of EEG abnormalities was not significantly associated with the presence or absence of psychosensory symptoms. Although it is not likely that panic disorder is an epileptiform disorder, temporal lobe and limbic structures probably play a major role in the pathophysiology of panic.
